This plugin generates the trend report for Checkstyle, an open source static code analysis program. 

Description

 
This plug-in is supported by the Static Analysis Collector plug-in that collects different analysis results and shows the results in aggregated trend graphs. Additionally, health reporting and build stability is also based on the aggregated results.

The Checkstyle plug-in scans for checkstyle-result.xml files in the build workspace and reports the number of warnings found (files from all Checkstyle releases are supported). This plug-in is part of the suite of static code analysis plug-ins that are documented on a separate WIKI page.

The following features are provided by this plug-in:

• Configuration of the files to scan after a build.
• Build summary showing the new and fixed warnings of a build
• Several trend reports showing the number of warnings per build
• Overview of the found warnings per module, package, category, or type
  • Parsing of Maven pom.xml or Ant build.xml configuration files to obtain the module or project name
  • Parsing of Java files to obtain the package or name space name
• Detail reports of the found warnings optionally filtered by severity (or new and fixed)
  • Short messages is read from the report file
  • Detailed description is read from the Checkstyle library
• Colored HTML display of the corresponding source file and warning lines:
  • Direct link to the warning line
  • Highlighting of single lines as well as line ranges
  • Highlighting of multiple line ranges per warning (different color for primary range)
  • Tool tip describing the warning message
• Failure threshold to mark a build as unstable
• Configurable project health support
• Remote API to export the build quality and found warnings
• Works with the freestyle and native m2 build option (activated on goal checkstyle:checkstyle or site)
• Several tokens to simplify post processing of the results
• Localization available for: DE, JA (Please help to localize checkstyle for your locale!)

The current release is available in the download section. This plug-in is developed and maintained by Ullrich Hafner. Please use the mailing lists or issue tracker to ask questions, create feature request or bug reports, since I don't read the comment section on this page regularly.
